Application filed March 23, 1922. Serial No. 545,960.

To all whom it may camera Be it known that Jenn SCHORR, citizen of the United States, residing at Davenporain the county of Scott and State of Iowa, has invented certain new and useful Im rovements; in Opening and Locking De vices for Closures, of which the following My invention relates to improvements in opening and locking devices for doors-foigarages, gates and similar applianees.

Th eb'eets or my invention are-taprovide a simple, practical, easily operated mechanism f r opening and closing sliding doors, etc, and fer lockin them openor closed position,

I attain these objects by the mechanism illustrated in the accompanying drawings, in which,-

Figure 1 is a lan view of my device Fig. 2 is a detail showing the side elevation of my device, but with the rim of the wheel in section; Fig, 3 is a side elevation of the outside postearrying the sheaves or pulleys for the cable; Fig. 4.: is a detail of the locking mechanism and Fig 5is a detail showing the means for securing the inner ends. of the door levers to theoperating wheel.

Similar numerals refer to similar parts throughout the several views.

M apparatus comprises a base plate, 4, which is suitably secured to the joists of a garage or building or structure by bolts-,5. A se mental rack, 32, is seeured'to joists of the structure by bolts or otherwise if desired. A bolt, 3, is secured in the plate, 4, and forms an axle for a wheel, 1, the hub, 2, of which is journaled on the axle, 3, and secured by a burr or nut, hubcap or other suitable device.

Levers, 16 and 17, have one end suitably secured to a fulcrum, 19, mountedupon and secured to the wheel by a clamp, 18, shown in Figure 5, by a bolt or other well known means.

In the drawings I have shown double spokes extending from the hub to the points of attachment of the clamps, 18, so as to enable the clamps to be more securely held in place, but these levers may be attached to the wheel by any of the well known means in common use for such purposes.

The opposite ends of the levers, 16'and 17, are secured to suitable brackets, 20, secured to the doors, 24 and 25, by bolts, screws or other suitable means, no claim being made of the usual we-ll known ways.-

here for any particular form of bracket. The doors, 245 and 25,- may be suspended upon rollers or mounted upon caster'sin any I make no claim for the particular iform of support for the doors;

The, Wheel, 1, is provided with. a concave rin r, 6, adapted to. receive-and carry an endless cable- 2 7, The cable is securedto'the locking device shownin- Figure 4 in the eye or hole, 8, formed the rocker bar, 9- The rocker bar, 9, is fulcrumed upon a pivot, 11. secured in the head, 7, 0% the locking device and the head, 7, is secured to the wheel, 1. bolts or, other suitable means.' Latches, 15 and: 15 ,-;are carried in slots formed in the head, 7, and held-in engagement by spiral springs, 14:. Links, 12 and 12,having enlarged heads, 10' and-10?, respectively, are hooked into the latches, 15-and 15, and pass through guide openings in the rocker The cablepass'es from. this eye,- 8, of the rocker bar, 9, in? each direction, partly around the wheel, 1', and passes over double pulleys or sheaves, 21V and 22, and around a single pulley, 2:3; The pulleys, 22 and are secured tothe post outside of the structure and the pulley, 21, is secured on the side or end of the structure above the doors, the cable passing out. through a suitable opening in" the end,- 26, of the building-or structure i In Figure 1 I'havef shown the doors in closed position in solid lines and have shownrthem' 1n openposition, 1n dottedlines.

In the operation of my device, when the doors are 1n the closed position as shown in Figure 1, one side of the cable on the post, 28, is pulled downward pulling the rocker bar, 9, to the left and unlocking the latch from the detent or notch, 33, allowing the wheel to revolve upon its axle and carry ing the head, 7, around to the position shown in dotted lines in Figure 1. The levers will then be as shown in dotted lines in Figure 1 and the doors open. To close the doors, the operation is reversed, the other side of the cable being pulled downward, thus revolving the wheel and closing the doors. When the doors are open,rthe latch, 15, drops into the corresponding notch in the rack, 32, and locks the doors against movement by wind or gravity.

For garages, I prefer to mount my operating wheel in a horizontal position, but it ating Wheel, of a lever having one end fulcrumed toa support secured to the operating Wheel and its opposite end secured to a door, and a locking head secured to the operating Wheel carrying latches adapted to engage notches o-r seats in a rack secured adjacent the Wheel.

2. In an operating device for sliding or rolling doors, the combination With an operating Wheel, of levers having one end fulcrumed to supports secured to the operating Wheel and their opposite ends secured to doors, and a locking head secured to the operating Wheel carrying latches adapted to engage notches or seats in a rack secured adjacent the Wheel.

3. In an operating device for sliding or rolling doors, the combination With an operating Wheel, of a lever having one end fulcrumed to a support secured to the operating Wheel and its opposite end secured to a door, a locking head secured to the operating Wheel carrying latches adapted to engage notches or seats in a rack secured adj acent the Wheel, a rocker bar fulcrumed in the head connected by links With the latches,

3 and means for operating the rocker bar so as to Withdraw the latches from their respective notches or seats in the rack.

4. In an operating device for sliding or rolling doors, the combination With an operating Wheel, of levers having one end fulcrumed to supports secured to the operating Wheel and their opposite ends secured to doors, a locking head secured to the operating Wheel carrying latches adapted to engage notches or seats in a rack secured adj a cent the Wheel, a rocker bar fulcrumed in the head connected by links With the latches, and means for operating the rocker bar so as to Withdraw the latches from their respective notches or seats in the rack.

5. In an operating device for sliding or rolling doors, the combination with an 0perating Wheel, of a lever having one end fulcrumed to a'support secured to the operating wheel and its opposite end secured to a door, a locking head secured to the operating Wheel carrying latches adapted to engage notches or seats in a rack secured adjacent the Wheel, a rocker bar fulcrumed in the head connected by links With the latches, and an endless cable secured to the rocker bar passing in both directions partially around the operating Wheel and over pulleys secured to a post accessible to manual operation.

6. In an operating device for sliding or rolling doors, the combination With an oper ating Wheel, of levers having one end fulcrumed tosupports secured to the operating Wheel and their opposite ends secured to doors, a locking head secured to the operating Wheel carrying latches adapted to engage notches or seats in a rack secured adjacent the Wheel, a rocker bar fulcrumed in the head connected by links With the latches, and an endless cable secured to the rocker bar passing in both directions partially around the operating Wheel and over pulleys secured to a post accessible to manual opera tion.

In testimony whereof I aflix my signa ture.
